Piezoelectric resonances in amino-acids.

Abstract: CRYSTALS of amino-acids may exhibit the property of piezoelectricity1–4 and, like other crystals, may belong to one of the twenty-one so-called piezoelectric crystalline classes5. Our particular interest in investigating piezoelectric resonances in amino-acids was in connexion with our current study of nuclear quadrupole resonances (NQR). For this purpose, it is preferable to choose non-piezoelectric amino-acids so that there is no interference in the detection of the quadrupole spectra6,7.
